Everything We Know About the Mysterious ‘516’ Pill That Could Replace Exercise

Mysterious pills that can “make us skinny” have long been a taboo topic. So when the new 516 exercise-replacement drug popped up, many were skeptical.

We did our research, so you don’t have to. Here is everything you need to know about the pill — as well as why people are concerned about it (page 7).

1. It’s supposed to break down fat

Ronald Evans, the lead researcher on the 516 pill at the Salk Institute in California, called 516 “exercise in a pill.” But what exactly does that mean?

Scientists have been working with the chemical compound 516 for years now and are convinced they can use it to alter the signals your genes send to your muscles, according to Esquire. So instead of breaking down carbohydrates, your body will break down fats — exactly what athletes burn when they exercise.

2. It’ll help people who can’t exercise

For many Americans, exercise is about willpower — and occasionally finances. However, for millions, it’s an unattainable task. Post-surgical patients, the extremely obese, and people with muscle-wasting diseases face serious challenges when they hit the gym.

“There are many reasons why people cannot run or walk or exercise,” Evans told The Washington Post. “If you can bring them a small molecule that can convey the benefits of training, you can really help a lot of people.”

3. You can control your weight without taking a step

Other drugs like 516 that can rid of exercise include compound 14, which works “by fooling cells into thinking they have run out of energy,” chemical biology professor Ali Tavassoli told Esquire.

But the 516 pill works as a “back door into the exercise genetic network,” Evans told The Washington Post. The “small molecule” will hopefully offer people the benefits of training without having to lift a muscle.

4. It would have to be FDA-regulated

The FDA doesn’t recognize being unable to exercise as an illness that requires a drug. That’s bad news for the people who would utilize 516 because they can’t exercise — not because they don’t feel like it.

Evans selected young people with Duchenne muscular dystrophy as his target demographic to gain FDA approval. “This afflicts kids who can’t exercise and ultimately die of muscle wasting, often at a relatively early age,” Evans told The Washington Post. “It’s a disease with a large unmet medical need.”

5. It might have the power to save people with acute kidney injury

The drug can help return compromised kidney tissue back to its previous healthy state and override irreversible organ damage. Acute kidney injury is a rare but fatal disease that afflicts people who undergo cardio-bypass surgery, according to The Washington Post.

“The organ or tissue changes its metabolic properties and begins to burn sugar, and because it happens quickly, it’s very hard to stop,” Evans said. “Our drug helps to draw the tissue back to a more healthy state, returning it from a chronic inflammatory damaged state.”

6. It could potentially treat diabetes

Because compound 14 — the similar “exercise pill” to 516 — breaks down sugar, it could potentially treat diabetes and metabolic syndrome in addition to acute kidney injury. Metabolic syndrome includes obesity, high blood sugar, and elevated bad cholesterol.

“The most startling results have been the effect of the molecule on glucose tolerance and body weight in a mouse model of diet-induced obesity,” Evans told The Washington Post. “It improves glucose tolerance and reduces body mass.”

7. There’s serious potential for addiction

The World Anti-Doping Agency already banned the experimental versions of 516 on the market. According to The New Yorker, 516 is still “multiple trials and several years away from reaching the market.”

And Evans isn’t trying to create a drug to turn athletes into “super athletes.” He told The Washington Post he’s sure the World Anti-Doping Agency would ban it. However, for those who struggle to exercise due to a disease or excessive weight, there’s a solution on the horizon.
